Galaxy clusters (GCs) are the largest and the most massive gravitationally bounded objects in the large-scale structure of the Universe. Due to the high (of the order of a few keV) temperature of virialized gas in the intracluster medium (ICM) and the presence of cosmic rays (CRs), GCs are effective sources of thermal X-ray and non-thermal lepton (synchrotron) radiation. GCs are also storage rooms for CRs because the time of CR diffusive escape from GCs exceeds the age of the Universe. However, non-thermal hadronic gamma-ray emission from GCs, which mainly arises due to proton-proton collisions of CRs and thermal protons of ICM plasma and the subsequent decay of neutral pions, has not yet been robustly detected. In this paper, we model the expected non-thermal hadronic gamma-ray radiation and neutrino flux from the Coma cluster (A1656) and evaluate the prospects for registering this radiation making use of available (Fermi-LAT, LHAASO, IceCube) and planned (CTA, IceCube-Gen2) ground-based detectors.
